IMPROVEMENT IN GRAIN-DRILLS.

Specification forming part of Letters Patent No. l 50,331, dated April 28, 1874; application filed March 23, 1874.

To all whom it may concern: v

Be it known that I, JACOB H. LANDIs, of Dayton, in the county of Montgomery and State of Ohio, have invented certain Improvements in Grain-Drills, of which the following is a specification:

My invention consists in an improved manner of attaching the receivers or grain conductors to the feed-cups of grain-drills; and is an improvement on the device patented. by Daniel E. McSherry, January 24, 1871, numbered 111,132.

Figure l is a side view of my improved apparatus, showing the receiver or grain-conductor attached to the feed-cup. Fig. 2 is an end view of the feed-cup, showing the relative position of the parts; and Fig. 3 is a perspective view of the cap or saddle which fits over the drivin g-shaft and distributing-wheel, detached and enlarged.

The receivers or grain -conductors A are made detachable, in order that they may be so placed as to cause the machine to deliver either forward or in rear of the feed-cups B.

In the patent above referred to, the receivers or conductors were attached to the feed-cups by means of hooks locking over the drivingshaft, said hooks being held over the shaft by means of springs. It has, however, been found, in practice, that this arrangement caused friction, and consequent wearing away of the driving-shaft.

The object of my invention is to obviate this difliculty.

In the drawings, B represents the seed-cup, which is attached to the bottom D of the hopper, as shown in Figs. 1 and 2, said cup having placed in it a distributingwheel, E, mounted on the driving-shaft H. The distributing-wheel E being placed in position, a cap or saddle, C, having one of its sides made beveling or inclined, is placed in a correspondingly-shaped recess, made in the sides of the feed-cup, over the driving-shaft H, as shown in Fig. l. The cap or saddle C having one of its sides made beveling or inclined, and fitting in a recess of corresponding form, wedges itself in place, and is supported by the seed-cup, so that it does not come in contact with the driving-shaft H. This cap or saddle is provided on one side with a curved lip, l, which forms a cover to the distributing-whcel E,

thus preventing the grain from falling from the hopper onto that side of the distributingwheel over which it projects, and prevents the grain from being carried around too far by the wheel, and also prevents the saddle from moving endwise in the feed-cup B.v The cap or saddle C is also provided at its ends with semicircular lugs or projections a, which extend out over the driving-shaft H a sufficient distance to allow hooks E on the receiver A to engage over them, which, together with the arm c on the receiver, securely lock the receiver tothe feed-cup B, the upper part n of the receiver resting against the upper part of the cup B, thus keeping the receiver steady and in its proper position. The hooks E are held over the lugs a by means of springs S, one end of which iits over a projection on the hooks, and the other in a recess made in the lug O, as in the device above mentioned. The distributing-wheel E being mounted on the driving-shaft H, is placed in the feed-cup B, and the saddle or cap C is then placed in position over them, the ears or lugs a coming nearly in contact with the shaft H. The cup B is then secured to the hopper D, which prevents the cap or saddle C from being removed from its seat, and this in turn holds the distributingwheel and shaft H. The receiver or conductor A is then attached to the cup B by means of the hooks E, which in this case are somewhat elongated in order to reach above the driving-shaft H, and over the ears a. In all other respects these hooks are the same as those heretofore used.

v It will be observed that this arrangement prevents the unnecessary friction and wear on the driving-shaft, which was an objectionable feature of the device before mentioned.

Having thus described my invention, what I claim is- The adjustable receiver A, secured to the feed cup B by means of the spring-hooks E, in combination with projections a on the cappiece C, all constructed and arranged to operatc substantially as described.
